STOPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 744,676, dated November17, 1903. Application filed June 19. 1903. Serial No. 162,151. (Nomodel.)

4 whichthe following is a specification.

' plan view of the locking-bar detached.

My invention relates to means for tempo-v rarily locking the stopper ina bottle; and it consists ofthe parts and combinationsofA parts, as willbe hereinafter more fully de: scribed.

In the drawings, Figure 1 is a vertical section of a bottle-neck withmy-improvedstopper partly inserted therein. Fig. 2 is a similar viewwith the stopper fully inserted in the bottle-neck and locked intoposition. Fig. 3

Ais a side elevation of the stopper and its lock detached from thebottle. Fig. 4 is a perspective Viewl of thestopper. Fig, 5 is a topFig. 6 is a section of the same on the line 6 6, Fig. 5.

7 represents the neck of a bottle broke awayand shown in section.

8 is an annular groove'formed on the inside of the neck of the bottle,near the top thereof. Said groove may be of any desired style oroutline, but is preferably one of the outline shown in the drawings-thatis to say, said groove extends slightly upwardly at the back.

9 isastopper,of cork or composition or other suitable material, .havinga suitable metallic disk 10 secured upon its upper side. While I haveshown the disk in the drawings as not extending entirely over the top ofthe cork,

at the same time it will be understood that said disk may be of the samediameter as the cork for the purpose of printing or stampingadvertisements upon the same.

11 is a stem passing throughthe plate 10 and the cork 9, the upper endof said stem being provided with an eye 12, in which is secured anextracting-riugl-. The lower end of this stein l1 is providedwith aT-head 14, tobe hereinafter referred to. I may, if desired, secure ametal'disk l5 upon the under side of the cork or stopper 9, throughwhich the stem 1l may pass, thus giving the stem a rigid non-yieldingbearing in the cork near itsupper and lower ends.

16 is a locking-har, substantially crescentits center.

shaped from end to end, in which there is provided aupelongated slot 17,situated near As will be seen .in Fig. 2, the locking-bar 16 is ofa-length greater than the diameter of the cork and the inside diameterof theneck of the bottle with which it is intended to be used, so thatits ends will project within the anuulargroove 8, formed on the insideof the neck 7 oflthebottle, Whereby said bar is locked within `the neckof the bottle. Corks will be furnished with the locking-bar attachedthereto and held in position by means of passing the T-head,14.'of thestem 11 through the elongated slot-17 and turning saidT-head at rightangles to the slot.

Withv the locking-bar thus attached to the cork the cork is started inthe neck of the bottle, `and by continued pressure, such as would bederivedfrom a corking-machine or by hand, the extreme ends of thelocking-bar are pressed upwardly'between the inner wall of the neck ofthey bottle and slightly info the cork 9, as clearly shown in Fig. l. Acontinued downward pressure upon the cork will shove the stem until theends of the lockingbar reach a point opposite the annular groove 8,whereupon said ends, by reason of the resilient nature of the materialof which the bar is constructed, will sprin g outward into the annulargroove 8, as shown in Fig. 2, and thereby will seat the bar in the neckof the bottle in the position shown in Fig. 2 against futuredisplacement-that is to say, the bar having been once sprung into thegroove 8 becomes a permanent fixture 0r part of the bottle, and byreason of its peculiar crescent shape it is adapted to withstand strainin pressure of gaseous or other expanding liquids'that may be placedwithin the bottle,

inasmuch as pressure on the vbottom ofthe am enabled to use a cork ofless depth, and

thereby economize in the cost of bottling.

Another` advantage resulting from my invention is that it is onlynecessary that the cork be sufficiently large to form an air and liquidtight joint between it and the neck of the bottle, as it is locked inits position against popping by means of the T-head 14: and thecrescent-shaped bar 16. Another advantage is that by reason of theshallow depth of the cork it is very easy to remove it by simplyrevolving the stem 11 until the T-head 14 alines with the elongated slot17, whereupon by a slight pull upon the ring 13 the cork may beextracted.

Having thus described my invention, the following is what I claim as newtherein:

1. The combination .with a bottle, having an annular groove in its neck,of a bar permanently looked in said groove and a cork constructed fordetachable connection with said bar.

2. The combination with a cork, of a locking-bar detachably securedthereto, and means permanently locking said bar Within the neck of abottle.

3. The combination with a cork and a T- headed stem secured thereto, ofa lockingbar detachably connected to said T-headed stem.

4. The combination with a cork and a T- headed extracting'steinconnected thereto, of a locking-bar detachably secured to said cork bymeans of said stem, and means permanently locking said locking-barwithinthe neck of a bottle.

5. The combination with a cork, of a locking-bar detachably securedthereto, and of a length greater than the diameterof the cork, adaptedto be compressed within the diameter of the cork when rst insertedwithin the neck of a bottle.

6. The combination with a bottle-neck having an annular groove in itsinner Wall, of a stopper, a stem secured in said stopper having anextracting-ring at its upper end, and the T-head at its lower end, and acrescentshaped locking-bar provided With an elongated slot and lockedpermanently Within the annular groove in the neck of the bottle, theT-head of the stem being adapted to pass through the elongated slot inthe locking-bar and be revolved at right angles to said slot, therebylocking the stopper to said lockingbar.

In testimony whereof I aiix my signature in presence of two Witnesses.
